The danger is very real, and serious. The reason we just saw a comprehensive multi-trillion dollar stimulus package is this paper by epidemiologist Dr Neil Ferguson and published today by the Imperial College of London showing that merely acting to slow rather than completely stop the spread would "still likely result in hundreds of thousands of deaths and health systems (most notably intensive care units) being overwhelmed many times over."

Their projection is for 2.2M (yes, million) deaths in the US.
That said, the Wuhan virus is spread not by speakers but by, uh, speakers. When you talk, or even breathe, it comes out in your breath. If you are infected. Which you must at this point assume that you are, and everyone else as well. Also assume every surface in the area of breathing people is contaminated, since moist breath and particles tend to drift and eventually settle on surfaces.
Wearing a mask interferes with this process. Virus that gets caught in the mask is virus not being deposited on surfaces. So avoid people, especially people so clueless or inconsiderate as to not be masked. Avoid touching surfaces anywhere anyone has been, because they could be contaminated. Above all wash and sanitize your hands like crazy and especially before eating or touching your face.
Do those things, maintain a distance of a good 6 feet, and there’s no reason not to go audition some gear. If that still somehow manages to be so important.
